Description

Technical Field

[0001] The invention belongs to the technical field of transport forklifts, and in particular relates to a transport forklift with an assembled shock-absorbing base. Background Art

[0002] A transport forklift is a common short-distance logistics transport forklift vehicle, which is mostly composed of a frame, a driving platform, forklift attachments, a hydraulic device, a gantry and other components. It is mainly used for loading and unloading, stacking and short-distance transportation of palletized goods. It has the advantages of large load capacity, simple structure, easy operation and maintenance, which can greatly improve work efficiency, reduce work intensity and improve productivity.

[0003] For example, a shock-absorbing forklift disclosed in national patent publication number CN111252703A has a structure including a forklift, a forklift mechanism, a door frame, a driving device, and a balancing counterweight. The forklift mechanism is composed of a backstop shelf, a fork, a storage mechanism, a transverse fence, a fitting mechanism, and a shock absorber. The forklift intercepts and blocks the goods on the forks by using transverse fences and vertical fences. The transverse fences are fixedly installed on the backstop shelf by positioning slide bars, and the goods can be prevented from sliding with the help of the supporting force on the backstop shelf. When the transverse fences and the vertical fences are not needed, the goods can be stored in the storage basket, thereby improving the convenience of use. The backstop shelf squeezes the goods on the forks by using the fitting mechanism to prevent the forklift from shaking too much on an unstable road and causing the goods to fall out of the forks. This design strengthens the protection of the goods, can reduce the occurrence of forklift accidents, prevent forklifts from damaging people or objects, and avoid property losses.

[0004] However, the conventional device still has the following problems when used:

[0005] Usually the center of gravity of a vehicle is maintained by the four tires to maintain the overall weight balance. However, due to the special structure of a transport forklift, when there is cargo on the fork mast, the overall center of gravity of the transport forklift will be more focused on the front tire position, which causes the swing axis of the cargo to be more biased towards the front tire of the forklift. When the road encounters bumps and potholes, the front tire is impacted by the bumps, and the center of gravity of the forklift body tilts again. At this time, the cargo and the fork mast supporting the cargo are not vertically bumped, but a diffused swing and bump formed with the front tire of the forklift as the axis. The cargo may collide or fall out of the fork frame due to unstable center of gravity, affecting the handling efficiency of the transport forklift and posing certain safety hazards. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the air compressor is started to increase the pressure, and the air pressure is filled into each balancing mechanism through the air supply pipe and the electromagnetic three-way regulating valve, so as to adjust the telescopic tension of the supporting plate, and an electronic level detector is set to keep each balancing mechanism flush. In this way, the supporting plate is kept flush with the fork frame, and the air pressure monitor is used to record the constant air pressure in the air pressure chamber at this time. When the forklift is bumped, the fork frame will swing with the front tire position as the axis of the forklift load-bearing bottom plate. At this time, the fork frame will be inconsistent with the horizontal height of the supporting plate due to the swing, resulting in a change in the pressure caused by the goods on the supporting plate. At this time, the air pressure monitor detects that the recorded constant air pressure value has changed, and the air compressor and the electromagnetic three-way regulating valve are used to adjust the pressure in each air pressure box in real time, so that the air pressure box always maintains the same horizontal position, the center of gravity of the goods is always stabilized at the shock-absorbing base position, and the spring damper is used to assist the air pressure adjustment to alleviate the vibration of the goods, thereby ensuring the stability of the goods.

[0019] 2. In the present invention, the infrared guide sensor light bar 1 and the infrared guide sensor light bar 2 are used as guide rails of the assembled shock-absorbing base, and the infrared guide sensor light bar 1 and the infrared guide sensor light bar 2 are used for real-time comparison and photosensitive calibration through the infrared counter-radiation sensor 1 and the infrared counter-radiation sensor 2 to ensure that the shock-absorbing base can always move forward relatively parallel to the fork frame. In the present invention, after the fork frame needs to assist in supporting the goods, the control console issues an operation command to start the two-way running motor to accelerate and drive the shock-absorbing base to move forward through the infrared counter-radiation sensor 1 and the infrared counter-radiation sensor 2 with the infrared guide sensor light bar 2 as the guide rail. When the shock-absorbing base moves forward to the transition zone between the forklift load-bearing bottom plate and the fork frame, the infrared counter-radiation sensor 1 moves along with the shock-absorbing base. The base is separated from the photosensitivity docking of the infrared guide sensor light strip 2 and then is photosensitivity docked with the infrared guide sensor light strip 1. During the docking period of the infrared counter-beam sensor 1, the guidance of the shock-absorbing base is maintained by comparing the infrared counter-beam sensor 2 and the infrared guide sensor light strip 2, thereby completing the front and rear displacement adjustment and guidance of the shock-absorbing base. The displacement stability of the shock-absorbing base is improved by the dual counter-beam sensors and the dual guide sensor light strips, and the non-rigid connection between the shock-absorbing base and the forklift is met, so that the shock-absorbing base will not be affected by the vibration of the fork frame. In addition, when the shock-absorbing base is recovered to the forklift load-bearing bottom plate chassis, the shock-absorbing base can provide a certain shock-absorbing resistance for the forklift load-bearing bottom plate, thereby improving the stability of the forklift load-bearing bottom plate when moving.

[0039] The working principle and use process of the present invention: In the present invention, when the fork frame 3 supports the goods, the center of gravity of the transport forklift shifts to the front tire position. At this time, the staff can move the assembled shock-absorbing base to the bottom of the fork frame 3, so that the assembled shock-absorbing base and the fork frame 3 support the goods synchronously. Since the fork frame 3 is not in contact with the connecting frame 5, the assembled shock-absorbing base and the forklift load-bearing base plate 1 are not rigidly connected and will not be affected by the bumps of the forklift. The center of gravity of the goods can be returned to the goods themselves. The "I"-shaped connecting frame 5 can provide better stability, and the use of multiple connecting bone plates 14 can enhance the longitudinal compressive resistance of the assembled shock-absorbing base. By installing rubber pads 15, the connecting bone plates 14 can be prevented from scratching the chassis of the goods. , and the rubber pad 15 has resilience toughness and can play a certain shock-absorbing effect. In the present invention, the air compressor 35 is started to increase the pressure, and the air pressure is filled into each balancing mechanism through the air pipe 31 and the electromagnetic three-way regulating valve 4, so as to adjust the telescopic tension of the supporting plate 7, and an electronic level detector 13 is set to keep each balancing mechanism flush. In this way, the supporting plate 7 is kept flush with the fork frame 3, and the air pressure monitor 9 is used to record the constant air pressure in the air pressure chamber at this time. When the forklift is bumped, the fork frame 3 will swing with the forklift load-bearing bottom plate 1 with the front tire position as the axis. At this time, the fork frame 3 will be inconsistent with the horizontal height of the supporting plate 7 due to the swing, resulting in a change in the pressure caused by the cargo on the supporting plate 7. At this time, the air pressure monitor 9 When a change is detected in the recorded constant value of air pressure, the air compressor 35 and the electromagnetic three-way regulating valve 4 are used to adjust the pressure in each air pressure box 6 in real time, so that the air pressure box 6 always maintains the same horizontal position, and the center of gravity of the goods is always stabilized at the position of the shock-absorbing base. The spring damper 8 assists in air pressure adjustment to alleviate the vibration of the goods, thereby ensuring the stability of the goods. The transmission pipe 34 is retracted and released in real time by the electric control reel 33, so as to meet the displacement of the shock-absorbing base from the bottom of the forklift load-bearing base plate 1 to the bottom of the fork frame 3, and the air transmission pipe 31 can be prevented from being dragged to the ground due to its excessive length. In the present invention, the strip-shaped infrared guide sensor light bar 1 28 and the infrared guide sensor light bar 2 29 are used as guide rails of the assembled shock-absorbing base, and the infrared counter-radiation The sensor 1 26 and the infrared counter-radiation sensor 2 27 compare the infrared guide sensor light bar 1 28 and the infrared guide sensor light bar 2 29 in real time for photosensitive calibration to ensure that the shock-absorbing base can always move forward in parallel with the fork frame 3. In the present invention, after the fork frame 3 needs to assist in supporting the goods, the console issues an operation command to start the two-way running motor 11 to accelerate and drive the shock-absorbing base to move forward through the infrared counter-radiation sensor 1 26 and the infrared counter-radiation sensor 2 27 with the infrared guide sensor light bar 2 29 as the guide rail. When the shock-absorbing base moves forward to the transition zone between the forklift load-bearing bottom plate 1 and the fork frame 3, the infrared counter-radiation sensor 1 26 and the shock-absorbing base are separated from the photosensitive docking of the infrared guide sensor light bar 2 29 and then perform photosensitive docking with the infrared guide sensor light bar 1 28.During the docking period of the infrared counter-radiation sensor 1 26, the guidance of the shock-absorbing base is maintained by comparing the infrared counter-radiation sensor 2 27 and the infrared guide sensor light strip 2 29, so as to complete the front and rear displacement adjustment and guidance of the shock-absorbing base. The displacement stability of the shock-absorbing base is improved by the dual counter-radiation sensors and the dual guide sensor light strips, and the non-rigid connection between the shock-absorbing base and the forklift is satisfied, so that the shock-absorbing base will not be affected by the vibration of the fork frame 3. Moreover, when the shock-absorbing base is recovered to the chassis of the forklift load-bearing base plate 1, the shock-absorbing base can provide a certain shock-absorbing resistance for the forklift load-bearing base plate 1, thereby improving the stability of the forklift load-bearing base plate 1 when moving. Since the handling forklift usually needs to work in factories, docks, and warehouses, the working environment will generate more dust due to transportation. After long-term use, the sensor elements of the counter-radiation sensor and the dual guide sensor light strip of the present invention will be covered with dust, which is easy to affect the guiding effect of the shock-absorbing base. Therefore, in the present invention, a cleaning sponge 25 is provided on the surface of the counter-radiation sensor to scrape and clean the counter-radiation sensor and the guide sensor light strip. The dust attached to the belt is wiped by the forward and backward movement of the shock-absorbing base to wipe the guide sensor light belt on the top surface of the cleaning sponge 25. Moreover, when the shock-absorbing base moves forward, the cleaning sponge 25 is located on one side of the opposite-shooting sensor, which does not affect the comparison of the opposite-shooting sensor. When the shock-absorbing base assists the fork frame 3 and then retreats to the bottom of the forklift load-bearing bottom plate 1, the cleaning sponge 25 is scraped by the top surface guide sensor light belt and slides in the limit frame 21 to wipe the surface of the opposite-shooting sensor. The synchronous wiping of the opposite-shooting sensor and the guide sensor light belt is achieved through the movement cycle of the shock-absorbing base. In the present invention, the rubber elastic belt 20 has a certain rebound tension, which can keep the fork frame 3 in a small degree of rebound fit when vibrating, and the fitting vibration of the limit frame 21 is offset by the flexible connection buffer of the rubber elastic belt 20, thereby reducing the vibration propagation. Moreover, after the cleaning effect of the cleaning sponge 25 becomes low after long-term use, the staff can tear off the cleaning sponge 25 through the set Velcro 24 for replacement to ensure the cleaning efficiency of the cleaning sponge 25.
